Zitat von Matth79 im Beitrag #483Where do the MSAHCI drivers fit in to this, while the AMD AHCI drivers are Win10 certified, they don't seem to have been updated since before Win10 came out.

The informations you get from the Device Manager are misleading, if you just right click onto the listed AHCI Controller and choose the options "Properties" > "Driver", because the shown version and date informations are just read from the related INF file, which hasn't been updated by Microsoft.

If you want to see the real version and date of the Win10 in-box MS AHCI driver named STORAHCI.SYS, you should navigate to the C:\Windows\System32\drivers folder, right-click onto the file named "storahci.sys" and choose the options "Properties" > "Details". This is what I get:As you can see, the generic MS AHCI driver of my Win10 v1607 ("Anniversary Update") has been compiled by Microsoft at 15. September 2016.

I was thinking the AMD drivers were also rather old (which they are), but with the MS drivers being more recent than they look, I think I should definitively switch back to them on my Netbook - and ignore IOBIT Driver booster!

Now I normally don't hold much with "driver updaters" as they are usually scareware that finds for free and charges to "fix", IOBIT does seem to be quite genuine and usable in free mode, and did do a decent job on some other drivers.But it was pushing to replace the MS standard drivers with ye olde 8.9.0.1023 Intel as it appeared to be more recent.

As for the AMD SATA drivers, the AMD download contains ..\W764A (Windows 7), WB64A (Windows 8.1) but NOT WT64A - so no Windows 10 specific, but Microsoft Update catalog does contain 1.3.1.276 for Windows 10, though not tagged for my device ID.

Guessing I'm probably best off with MSAHCI on both of them

Main system, Phenom II 965BE on M7A89GTDPRO/USB3 Win10Netbook, Atom N450 on NM10 (with Intellimoder GMA3150 driver, wow what a difference), Win10Various other old clunkers, 2x P4 also on W10

@Pacman:Thanks for the info and the links.The most interesting new Samsung NVMe driver seems to be the v2.4.7.0, because it obviously supports the same Samsung NVMe Controller as the old v1.4.7.17 drivers.As soon as I have the required time I will test these new Samsung NVMe drivers with my Z170 system running Win10 x64. If they should work, I will offer them within the start post of this thread.

Zitat von Arnie im Beitrag #488@PacmanYou sir are a savior doing God's work!!! I've been looking for the SM961 drivers for about a week. I was about to give up and install Win10 on a Lenovo T460s. Thank you! thank you! thank you!

Yes, ok for Samsung SM961 and 950 Pro (driver HP)

Thanks so much Pacman ;)

EDIT: Less efficient than the Samsung official driversI will wait for the official drivers :)

Thanks to Pacman for the link to the Installer Set.Notes:The included 32/64bit Samsung NVMe drivers are dated 08/04/2016, WHQL certified by Microsoft and seem to be usable with all Windows Operating Systems from Win7 up.Supported are the Samsung NVMe Controllers with the DeviceIDs DEV_A802 and DEV_A804, which are within Samsung's most popular consumer NVMe SSDs like SM951, SM961, SM961 SED, PM961 and 950 Pro SSDs.RegardsDieter (alias Fernando)

Zitat von bigplus im Beitrag #114I've just tested new: 32/64bit Win7 AMD AHCI drivers v1.2.1.376 WHQL dated 09/23/2014, suitable for AMD AHCI Controllers DEV_ 4391/4394, DEV_7801/7804 and DEV_7901/7904Well, everything went slower again.Rolled back to 64bit Win7 AMD AHCI driver v1.2.1.359 WHQL and restarted, everything runs smooth and fast.The difference is so conspicuous, like if I take 4Gb RAM off and then put it back again.Still wondering how come 100Kb junk of driver files can make such a good speed improvement. Maybe Win7 AMD AHCI v1.2.1.359 WHQL driver was coded by some smart developer, who already left the company or maybe it is only a coincidence relating to my laptop's model and OS configuration.

I would recommend to recover and keep AMD AHCI v1.2.1.359 driver links open, so other people could test an overall performance on different PC/Laptop models.

Hello bigplus & Fernando!

I hadn't recognize any big differences between AMD AHCI driver v1.2.1.359 WHQL and AMD AHCI driver v1.2.1.402 WHQL with HDDs on SB750 systems and HDDs/SSD on SB950 systems with Win7 64bit.Seems, that the info is old now. I can make benchmarks, if it's needed.

@FernandoAlthough there is a bug in your website. The link to bigplus' post is set under Win8.x/10 -> that make no sense to me.

@NIK1:Thanks for the info and the link. Unfortunately I have not yet been able to extract the "pure" Samsung NVMe drivers.As soon as I have the time, I will test and compare them with the already available Samsung NVMe drivers v2.4.7.0.
